对于PHP,有像mysql_insert_id()这样的Ruby选项吗？

<?php
// 创建连接
$dsn = "mysql:host=localhost;dbname=testdb";
$username = "username";
$password = "password";
$pdo = new PDO($dsn, $username, $password);

// 插入记录
$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (?, ?)");
$stmt->execute(["John Doe", "john.doe@example.com"]);

// 获取最后插入记录的ID
$lastInsertId = $pdo->lastInsertId();
echo "Last inserted ID: " . $lastInsertId;
?>
